RAILROAD-RAIL CHAIR.

SPECIFICATION forming part of Letters Patent No.355,7'79, dated January 11, 1887,

Application filed April 14, 1886.

To all whom it may concern:

Be it known that I, ARTHUR J. MOXHAM, of Johnstown, in the county of Oambria and State of Pennsylvania, have invented a new and useful Improvement in. Railroad -Rail Chairs, which invention or improvement is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to make a chair of wrought metal which shall be capable of tightly fitting into and clampingthe webs of rails provided with stubs or beaded edges at the bottom of said webs.

The invention consists of the article of man r 5 ufacture as hereinafter described, .and set forth in the. claim.

Figure 1 shows awrought-ironchair in perspective. Fig. 2 shows a wrought-iron chair, also in perspective, but having its standards formed all in one piece with the rest of the chair, instead of in separate pieces, as shown in Fig. 1.

In said figures the several parts are indicated by letters, as follows:

The letter E indicates a plate having as part thereof the two standards A A diagonally placed and of such form that the upper parts a a of said standards bear with a neat fit against shoulders upon either side of the web of the 0 rail. (Not shown.) The spike-holes F F are placed diagonally, two only being shown; but more may be added, if deemed advisable.

The standards A A in Fig. 1 may be either drop-forged or rolled to the required shape,

5 and are secured to the base-plate Eby rivets b b.

Fig. 2 shows a wrought-metal chair, also of shape like that shown in Fig. 1; but the stand-. ards A A in this case are stamped out of the metal E, the spaces left by such stamping being 0 indicated by the letters H H. Said standards,

, having been thus stamped or punched out, are then drop-forgedto shape. This is the preferable mode of manufacture, Fig. 1 showing only a modification.

In each of the variations of structure above shown the principle of operation and location of the standards A A are the same. Said standards are diagonallylo'cated, and are each offset, as shown, to neatly fit'over the stub or l fillet of the web of the rail. Such location of said standards, by providing a sufficient dis.

missible, and such variation and adjustment Serial No. 198.786. (No model.)

tance between them, permits thelower stub, G, of the rail to enter said chairs between their two standards A A. Their distance apart in a straight transverse line is such that when 5 said standards are brought to a true plane with the rail the parts a a fit snugly and neatly into the rail under its shoulders on either side of its web, and also make a similar fit over or upon the stub or lower fillet of said web.

When the track is beinglaid, the chairs are slipped diagonally into place over the rails, and the spikes, which, diagonally placed, secure the chairs in track, are then driven in and hold them true to a fit to the rails, as before described. The chairs thus held, the subsequent bonding of the road-bed material or ballast around them serves to further secure said chairs in place.

The considerable advantage of this form of chair lies, in the fact that great facility is afforded for placing such chairs at any point. in

the length of the rail. Where chairs are used which are bolted through the webs of. the rails in securing the rail and chair together, although the necessary holes are drilled at the works or shops previous to shipment, yet such method of fitting necessitates the adoption of exact points where only the chairs, and, consequently, the cross-ties, can be placed when the construction of the track is progressing.

'In constructing the track it is found to add considerably to the costto be compelled to exactly locate the cross-ties for the chairs, as in the case above mentioned must be done. The excavations for the crossties being generally made by ordinary day laborers, such unskilled labor, if compelled to work to much exactness, is usually slow and uncertain and loses much time in making mistakes. Exactness of location of cross-ties, therefore, if demanded, becomes an item of considerable cost. The best method, therefore, is one in whichv slight variations of cross-tie spaces are perof distances isrendered quite feasible and facile by the form and construction ofchair hereinabove described as the subject of this invention. The time and cost of securing the bolts and nuts in the usual construction of chairs provided with standards is also saved, which is quite an item in saving, as there are from seventeen hundred to two thousand chairs at- I vided with diagonally-placed standards ofi'set taehed t0 the rails for every mile of track. to clamp the web of the rail over the stub or Y I am aware that diagonal lugs for clamping beaded footof said web,v and, while free to be the edges of the lower or base flanges of rails entered diagonally on such rail, fits into and 15 5 have heretofore been used, and such I do not I ties the same when spiked down true thereto claim; but, in the track, substantially as and for the pur- Having thus fullydescribed my said railposes set forth. chairs, as of my invention I clain1 As a new article of manufacture, a railroad- Witnesses: 1o rail chair of wroughtmetal struck up and drop- I WV.
